BRYOE A. WILSON, OF PROVIDENCE, RHODE ISLAND.

Box-Loop AND BLIND FOR HARNESS.

- SPECIFICATION forming part of Letters Patent No. 260,074, dated June 2'?, 1882, 4

Application tiled January 13, 1882. (No model.)

To all whomtt may concern:

Be it known that I, BEYcE A. WrLsoN, a

citizen ot Great Britain, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new Vand useful Improvements in Box-Loops and Blinders for Harnesses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference represents the box-loop and blinder with por-j tions of the same broken away and viewed from the back side. Fig. 2 is a section through x w of Fig. 1, enlarged, showing the arrangement of the parts constituting my invention. Fig. 3 is a modification of the parts shown in Fig. 2. Fig. 4 represents the metallic blank from which the box-tube is formed, reduced scale. Fig. 5 represents the metallic blank which serves to connect the -`box-tube, loop, and blinder-iron rigidly together, also reduced. Fig. 6 is a section through wx, a: of Fig. 1, showing the relation of the metallic connecting-piece, Fig. 5, `to the loop, enlarged scale. Fig. 7 represents the blinder-iron, small scale.

a is the box-tube covered with leather a and a3. The tube-frame a2 is made of sheet metal, cut in the form shown in Fig. 4, having a series of slots, o, near each edge. Said tubeframe is bentlongitudinally and into the form shown, the slots o o resting one above the other. b represents the usual box-loop, made of leather.

c, Fig. 5, is a blank, cut also from sheet metal, which, being longitudinally bent and folded, assumes the form shown in Figs. 2, 5, and 6. .At suitable distances the blank o is and forced along the space e of the tube, the

sh ank o' projecting through it. Then place the slots of ot' the blinder-iron d over said shanks, after which the box-tube a is inserted over the shank o2, which now brings the parts iu position to be swaged or pressed together. This operation is performed by inserting an arbor or mandrel into the loop b. The edges o2 are then bent downward, when another arbor is inserted into the box-tube a. and all the parts compressed together by means of a suitable press.

It will be observed that in compressing 4all the parts together the spurs c3, Fig. 2, are embedded into the leather box-loop, eectually preventing the latter from workin g loose laterally. A loop of wire or thread, zo, may also be introduced, as shown in Figs. l and 6 at o4, to still further retain the box-loop together.

It will further be observed that I dispense with all soldering or brazing iu securing the parts together, thereby materially reducing its cost of manufacture, and still further increase the strength and stiffness of the tube, 8vo., by overlapping the under side of said tube a? and by bending the plate c back upon itself, as shown in Fig. 2.

.In Fig. 3 is represented a method of securing the tube, blinder, and loop together by having the tube with its shank, &c., formed from a single blank. By adding the wire loops w a very-strong and at the same time a cheap article is`produced.

I claim as my invention- 1. The tube-frame a2, with its slots c, in combination with the notched and punctured metallic T-shaped piece o of the box-loop b, all substantially as described, and for the purpose specied.
